Title: Improvements relating to means for operating sliding vehicle windows and like closures
IPC: E05F11/38
Filed: 1943-08-12
Abstract: 568,425. Linkwork. TRICO PRODUCTS CORPORATION. Aug. 12, 1943, No. 13094. Convention date, Aug. 13, 1942. [Class 80 (iii)] [Also in Group X] A vehicle or like sliding window is raised &c. by a band passing over pulleys 14 ... 17 and connected to a piston 21 operated by fluid pressure from the intake manifold of the motor engine. Depression of the window from outside is prevented by brakes 34, Fig. 4, acting on the cylinder wall by movement of the band. The brake blocks and encircling rings of resilient material 36 are actuated by toggle-shaped springs 35 mounted on a plate 38 bearing against a flange of the band attachment 31. The left hand piston part 29 provided for normal lowering movement of the sash has a gland 30 slidable on the connector 31 and has a ring 40 connected thereto by rivets 41. The ring engages the brake blocks and the springs 35 on opposite sides and frees or applies the brakes when movement is initiated by the piston and by the band respectively. In a modification, Fig. 7, the brake blocks may be actuated by rigid toggles 73 and a weak helical spring 74. The ends of the band have U- shaped strips riveted thereon. As shown in Fig. 7, the band attachment may be fixed in a sleeve 61 by the nut 64 and flanged lock-nut 65 which also secure the piston on flats 63. A flat 75 and recess in the sleeve prevent relative rotation of the parts. The band passes through packing pieces at each end of the motor. To equalize the pressure between the piston parts and the space outside small ports 78 and 79 are provided, the port 79 being covered by a plate 80 held beneath the lock-nut 65, Fig. 7.

Title: Improvements in or relating to regulators for electric power supply systems
Inventor: KELLY RICHARD

Abstract: 638,505. Rectifiers ; automatic control systems for voltage ; automatic regulation. STANDARD TELEPHONES & CABLES, Ltd. May 15, 1947, No. 13100. [Classes 38 (ii) and 38 (iv)] In a voltage regulating system for supplying a load from an A.C. supply, a saturable reactor, in series with supply and load, has control windings D.C. excited from the supply and the load terminals. As shown, the D.C. load terminals 3, 4 are supplied from the A.C. source 1, 2 through the transformer 5 and rectifier bridge 6. The A.C. winding 7, of the saturable reactor 8, is in series with the primary 5a of the transformer 5, the control winding 15 is energized through the rectifier 17 from the source, the control winding 14 is energized from the load terminals while control winding 9 carries a fraction of the output current determined by the value of resistor 11 of regulator 10. A rise of D.C. output current lowers the reactance of 8, a higher voltage is applied to winding 5a which compensates for the increased voltage drop in rectifier 6 due to the rise of load current. A rise in the voltage at the output terminals 3, 4 is supplied to coil 12 and lowers resistor 11, the current through 9 falls and the voltage at 5a is reduced to correct the D.C. output of 6. The fluxes due to coils 14, 15 are opposed and are balanced at the maximum value of supply voltage, a fall in the latter causes a resultant flux which lowers the impedance of 8 and hence raises the voltage at 5a. In a second embodiment, not shown, an A.C. load is supplied through a transformer from an A.C. source. The two control windings of a saturable reactor, which is in series with the transformer primary, are separately energized through rectifiers, from the source and load terminals and are mutually opposed so that their fluxes balance when the supply voltage is a maximum. A fall in supply voltage is therefore accompanied by a lowering of the reactor impedance with a consequent rise of voltage at the transformer primary. Final adjustment to the output voltage is effected by a resistance regulator which is in series with the control coil associated with the supply and which is actuated by the load voltage. Specifications 599,018 and 613,866 are referred to.

The backing sheet may form part of the final product of the resulting sheet of a woven or knitted fabric. Suitable resins are butadienestyrene copolymers, polychloroprene, polyvinyl chloride, polyvinyl acetate, and vinyl chloridevinyl acetate copolymers. The fabric may be of cotton, wool, asbestos, glass or synthetic fibres. It may be pre-impregnated before application of the resin composition with vinyl resins such as vinyl chloride and vinyl acetate polymers, particularly copolymers of these, polymers of acrylic and methacrylic acids and esters, polyethylene, polystyrene, butadiene-styrene copolymers, butadiene-acrylonitrile copolymer, polychlorprene, natural rubber, phenolic resins, polyesters, oleoresins, such as cured, dry and semi-drying oils, isocyanates and polyurethanes. Numerous suitable copolymers for the resin layer are specified. The composition may be in the form of a plastisol or an organosol and many suitable plasticisers and stabilisors are specified. Numerous suitable hydrazine derivatives are listed such as hydrazodicarbonamides. The oxidising agent may be a positive halogen oxidising agent, a peroxide compound, a quinone compound, a quinone chloroamide, a dialkyl sulphoxide or an inorganic oxidising agent. The oxidising composition may be pigmented. Accelerators or catalysts may be present in the pigmented layer for which a vinyl polymer may be present as a carrier. A second layer of resinous composition which may be the same or different from the first coating may be applied before or after the foaming step.

[Class 40 (iv)] [Also in Group XL (b)] - Cross-talk is equalized between two circuits having different transmission characteristics and overlapping carrier bands by regulating the input levels of signals in one of the circuits. If a narrow-band twisted-pair circuit and a wide-band coaxial circuit, having carrier bands from 12 to 108 kc./sec. and from 60 to 1052 kc./sec. respectively, are in cross-talk relation in the overlapping part, 60 to 108 kc./sec., of their ranges; and if all frequencies in the narrow band have the same input level R, Fig. 2 (P), and all frequencies in the wide band have the same input level M, Fig. 2 (C); and if the repeaters are so adjusted that the signal of highest frequency in each range reaches the output end at a prescribed level Q above noise; then the level at the upper limit 108 kc./sec., in the narrow band will, throughout the length L of the circuits, be at levels MF in the wide-band circuit which are higher than the corresponding levels RQ in the narrowband circuit, so that the wide-band circuit is more likely to interfere with the narrow-band circuit than vice versa. To equalize the levels of signal above cross-talk in the two channels, the level at the frequency in question is lowered from M to D at the input end of the wide-band circuit so that the levels become DE instead of MF. The difference MD in input levels is made equal to half the difference between the attenuations of the highest and lowest frequencies in the wide-band circuit. An analogous arrangement is made in the case in which the level of output signals is made constant throughout each of the frequency bands; in this case the characteristic MF has to be raised instead of lowered, Fig. 3 (not shown): Similar arrangements are made for each frequency in the overlap band. The setting of the levels may be effected by attenuation in the negativefeed-back path in an amplifier, supplemented by attenuation in a pad such as that illustrated in Fig. 4 (not shown) and Fig. 5.
